Re: lily 1.3.111

[Mats Bengtsson]

I addition to the new features, there are also som bugs.
For scores with StaffGroups, and GrandStaffs, you get the
following kind of warning and no brackets or braces are
produced in the output:

Failed typecheck for `glyph', value `bracket' must be of type string
Failed typecheck for `glyph', value `brace' must be of type string

The following patch seems to solve the problem, but I'm not
sure it's the best way to solve it (clef glyphs are strings
and SystemStartDelimiter glyphs are symbols at the moment).
